The discrete methods for solutions of continuous-time systems
The first part of this contribution deals with discretizing differential equations. Difference equations can also be obtained by discretizing differential equations. A first order differential is approximated by a first order difference, a second order differential by a second order difference, etc. The other way of discretization is discretization by Z transformation of transfer function G(s). This contribution is concerned with the Euler’s method and bilinear method. The contribution solves the link between s and z.
The last part of this contribution contains solutions of unit step response and impulse response of continuous-time systems by discrete methods that were introduced here.
The contribution shows the new possibility of how to solve continuous-time control systems by discrete methods.
